The Future of Computing - Cloud

Cloud computing is a technology that uses the internet and central remote servers to maintain data and applications. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. This technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth.

Simple Example is Gmail and Yahoo..etc..What technologists like to call "the cloud" is the idea of computing on demand. Indeed, the cloud is accessible through any digital device such as a laptop, a cell phone, or a smartphone that can connect to the Internet.
The Cloud is a global connector to the world's information and users. The result is a dramatic advance for users in accessibility, specialization, collaboration, and ubiquitous access to processing power and storage.

Cloud Computing broken down into three segments,

• Applications
• Platforms
• Infrastructure 

Cloud computing users avoid capital expender on hardware, software, and services when they pay a provider only for what they use. Consumption is usually billed on a utility or subscription basis with little or no upfront cost. In Cloud computing give lots of benefits such as low barriers to entry, shared infrastructure, costs, low management overhead, and immediate access to a broad range of applications.
